/**
 * <code>Search</code> is used to define search parameters when looking for a
 * particular user. For example to search for a user with the last name of smith, you
 * use the following line:<br>
 * <pre>
 * search.setLastName("smith");
 * </pre>
 * However to get a list of all users whose last names begin with 'sm', you would do
 * the following.<br>
 * <pre>
 *  search.setLastName("sm");
 *  search.addSearchOperator("LastName",Operation.LIKE);
 * </pre>
 * If no operation is defined for a given attribute, the '=' operation
 * is assumed.
